Yes....but some ships have started charging a 3% surcharge for this. Not sure if RCCL is doing this - but if one starts, can the others be far behind.
Be sure and ask the ships' policy so you won't get any surprises on bill the final night!

Remember that a 3% service charge for cash advances from the Casino can be cheaper than what one may have to pay at an ATM machine when two (or more) financial house are involved with the ATM transaction. It will depend on the amounts taken but something to consider.

no they don't charge extra for cash advances in the casino and according to a pit boss they are not thinking of doing it . if you gamble the tables are awful i play for three nights on the single deck and multi deck b/j no one was a winner i only heard one winner on the slots the poker table was 3 and 6 no limit there was a person that raise every hand and everyone was dropping out if it was just 3 and 6 i would had play . the schonner bar is now non smoking that's the bar next to the casino so the smoke from the casino drifts into the bar strange if you need any more info just post a reply and i get to it by the way the atm machine was least 6 dollars to get your own money
